Boeing flights grounded across globe, but not in U.S.

With more countries grounding Boeing jets and with lawmakers, aviation workers and consumers calling on the United States to do the same, the head of the aerospace giant on Tuesday made a personal appeal to President Trump. Boeing’s chief executive, Dennis A. Muilenburg, called from Chicago and expressed to Mr. Trump his confidence in the safety of the 737 Max 8 jets, according to two people briefed on the conversation. Two of the planes flown by overseas carriers have crashed in recent months in similar accidents.

By Tuesday afternoon, the United States was nearly alone among major countries still allowing the jets to fly.
